Rising Film Evaporator Manufacturer: A Rising Film Evaporator (RFE) is a vertical shell and tube heat exchanger with a vapor – liquid separator mounted at the top. The liquid to be concentrated is fed at the bottom of the heated tube bundle. As the liquid feed receives the heat, the vapors generated lift the liquid upwards and push it on the wall as a film. The velocities generated by the vapor lift are quite high, giving good thermal performance. The balance liquid and vapor are separated in the vapor- liquid separator. 'Simple solution for concentration of liquids that are moderately heat sensitive' FEATURES Thermosiphon action due to boiling in vertical tubes eliminates the need for circulation pump Trace quantities of suspended particles in the feed are tolerated Can operate under reasonable vacuum Multiple effect arrangement provides steam economy APPLICATIONS Concentration of dilute solutions containing water and organic solvents in applications such as plant extracts in water or organic solvents As a reboiler to distillation column Economical alternative to falling film evaporator for moderate vacuum and moderately heat sensitive products See More- http://www.spraydryerindia.com/rising-film-evaporator.html
Forced Circulation Systems Manufacturer: We offer forced circulation systems that is used for various applications related to crystal growth and mother liquor de-super saturation. The forced circulation systems is provided with a specially designed liquid vapor separation area that avoids formation of an excessive amount of fines, which is highly detrimental to crystal growth. Construction: An "active volume", designed case by case, to get both required residence time for crystal growth and mother liquor de-super saturation A given agitation (recirculation rate) rated to control the extent of super saturation arising from the evaporation, and to keep the temperature difference in the heat exchanger within reasonable limits Provided with liquid-vapor separation area to minimize the carry over losses and avoid the formation of an excessive amount of fines, which is highly detrimental to crystal growth Forced circulation Evaporator is used where boiling of the product is steering clear due to its bad foul characteristics. When the mixture flows through the heat exchanger it get partially vaporized because of the decrease in pressure. In this process powerful circulation pump forces the liquid through the help of tubes. The heat is picked by the shell side which carries steam. The height of the liquid is designed in a way thio stay away from the nucleate boiling inside the evaporator tube bundle. This type of equipment can be mounted vertically or horizontally according to the client’s need. Additionally they can also strengthen the solid substance into the liquid but before drying. They ensure moisture free complete process. But in this high power pump as well as high flowing velocity in the tubes are required. The efficiency of forced circulation evaporators is completely dependent on the heat temperature of the steam and the solution. Advanced Drying System. have a total quality management system that has the responsibility of matching the designs of our products to the international market standards. We integrate those forced circulation evaporator design to deliver the best quality service from our side. Meticulous Features Of Forced Circulation Evaporator: Ideal For Crystallization Concentrated Values Steam Economy Multiple Arrangements For High Performance High Capacity Minimum Consumption Of Energy Applications Of Forced Circulation Evaporator Waste Water Concentration Concentration Of Inorganic As Well As Organic Salt Solutions Evaporative Crystallization Network Area: Our manufactured products are made up of finest quality of raw materials due to which it ensures durability in the product nature. There are mainly three factors in our designed products which are the main keys of our success and these are quality designs, competitive price and timely delivery.

Vibrated Fluid Bed Dryers Manufacturer: The vibrated fluid bed dryer is used for fluidization of materials which are difficult to handle in a static fluid bed dryer. These materials are often characterized by having one or more of the following physical properties: Wide particle size distribution Low strength of wet or dry particles Stickiness or thermo plasticity of the particles Pasty properties of the wet feed In the vibrated fluid bed dryer, the material is easily transported through the dryer by the combined effect of fluidization and vibration. The fluidization velocity can be judiciously selected, to minimize entertainment of the smaller particles, to avoid gas bubbling m the fluid bed thereby minimizing attrition. The residence time can be adjusted, by varying the bed height, through the overflow weir position. A cooling section can also be provided, by partitioning of the plenum chamber. Typical products handled Salt Milk products (used as a secondary dyer) Chemicals Tea . See More- http://www.spraydryerindia.com/vibrated-fluid-bed-dryer.html
Flash Dryers Manufacturer: Flash dryers offer an effective and efficient method of removal of surface or on bound moisture from a feed product. Flash dryers are pneumatic driers having very low residence time within the equipment, thus flashing off the moisture from the feed. They are used for efficient drying of moist powders. Slurry, filter cakes, granules, etc. They operate on varying throughput rates from few hundred kilograms per hour to hundreds of tons per hour. Low temperature dehumidified air could be used for heat sensitive products to hot gases with temperature up to 500 - 600 deg. C. For temperature resistant products. Flash dryers comprises of the feeding section normally a screw feeder, rotary valve, vibratory feeder, etc. Which feeds the wet product in a controlled fashion into the throat of the flash drier, where it is mixed with hot air produced by a hot air generator or heat exchanger. Flash Dryers are characterized by short residence time of few seconds. Hence, great care needs to be taken in dispersion of the feed in the drying air, which is generally in the form of cake so that true surface water gets evaporated form the feed . Otherwise, the larger particles in the feed material may require longer drying time than the smaller ones in order to reach the desired moisture content.

Laboratory Spray Dryers Manufacturer: The laboratory spray dryers is a totally self contained unit and is supplied ready for immediate operation. The laboratory spray dryers unit is compact and can be kept on a table top or bench. The solution or suspension is converted to powder in a single operation. The unit can be used to establish new products/processes as the quantity of sample required is small, only 50 to 100 ml. Principles: A peristaltic pump delivers liquid from the sample container to the fluid nozzle mounted on the drying chamber. Compressed air from the inbuilt compressor is also supplied to the nozzle, resulting in atomization of the liquid into a fine spray. Air from the blower is heated by an electrical air heater and blown through the drying chamber. Due to the large surface ;area, drying is very rapid, resulting in a sharp drop in temperature. The dry powder particles are separated from the air in the cyclone separator and collected in the glass collection bottle. The exhaust air is directed through a flexible ss hose into the atmosphere. A bag filter can be provided for secondary powder collection. Construction: the blower, electrical air heater, air compressor and the pump are placed in a stainless steel panel, with free and easy access. the air entering the panel is filtered through a fine cloth filter. the chamber and cyclone are of borosilicate glass with clamp fittings, designed for easy assembly and removal. the peristaltic pump is mounted on the front of the panel with easy accessibility.
